Description
Technical Field
The utility model belongs to the technical field of reconstituted tobacco production and processing, concretely relates to device of reconstituted tobacco is prepared to multiple spot air inlet formula thick paste method.
Background
With the acceleration of global tobacco control movement, the global tobacco industry enters a new period of seeking revolution and breakthrough, and further promotes and accelerates the research and development of novel tobacco products, such as heating non-combustion cigarettes, electronic cigarettes, buccal cigarettes and the like. The cigarette is an important component of the novel tobacco product.
Compared with the granular and traditional tobacco shreds as tobacco section materials, the reconstituted tobacco leaves have the characteristics of stronger plasticity, homogenization and higher adjustable level while keeping the active ingredients of the natural tobacco leaves, so the reconstituted tobacco leaves are one of the main tobacco section materials for heating non-combustible cigarettes at present.
When the tobacco sheet is formed by the thick pulp method, the tobacco raw material powder, the adhesive, the smoke agent and other materials are uniformly distributed on the surface layer and the inner layer of the tobacco sheet, so that the thickness and quantitative stability, the heat conduction uniformity and the smoke effect of the tobacco sheet are better, and the tobacco sheet is one of the main reasons for being a tobacco section material of a cigarette which is not combusted by heating. Such as: the iQOS cigarette developed by Felmo tobacco company adopts orderly arranged thick pulp method to reproduce tobacco leaves.
In the drying stage of preparing reconstituted tobacco by a thick pulp method in the prior art, a method of heating and heating the lower part of a conveyer belt is utilized to evaporate water in a pulp membrane paved on the conveyer belt and overflow the water into an upper ventilation tunnel due to heating, and hot air in the direction opposite to the conveying direction of the pulp membrane (in a reverse flow) is utilized to bring the evaporated water out of equipment to meet the requirements of a dehydration process. The problem that it exists is that the hot air inlet is only one, and the closer to the initial section of the drying process, the hot air already absorbs a large amount of moisture, resulting in the weaker moisture absorption capacity and the poorer drying efficiency.
CN109405506A discloses an incremental hot air countercurrent drying device (see fig. 1), which comprises a conveyor belt 5, wherein the existing heating device is uniformly arranged below the conveyor belt 5, a ventilation tunnel 6 is arranged above the conveyor belt 5, 4 ventilation openings are arranged on the ventilation tunnel 6, an air supply pipeline 7 is communicated with the 4 ventilation openings, hot air enters the ventilation tunnel 6 from each ventilation opening and then is exhausted out of the drying device through an air outlet 8, wherein the first ventilation opening 1111, the second ventilation opening 2222, the third ventilation opening 3333 and the fourth ventilation opening 4444 are all perpendicular to the conveyor belt 5 and are sequentially arranged from the right end to the left end of the ventilation tunnel 6, and the sectional area of the ventilation tunnel is gradually increased along the wind direction. It has the problems that: in the process that hot air flows from right to left in the ventilation tunnel 6, the air volume is increased gradually, the hot air volume Q4' at the leftmost end of the ventilation tunnel 6 is Q1+ Q2+ Q3+ Q4, in the practical application process, the pulp flowing out of the head box (with higher water content of 70% -80%) forms a pulp film firstly, and in the process that a conveying belt runs from left to right, the pulp film is dried gradually to form a reconstituted tobacco leaf sheet, so that the leftmost end of the ventilation tunnel 6 in the device is just the pulp film forming process of the pulp, the pulp water content is high, the leveling property is good, and at the moment, if the air volume is large and the wind direction is vertical to the direction of the pulp, the thickness of the pulp film formed by the pulp is inconsistent, the pulp film is thinner at the position close to the ventilation opening, the pulp film at the position far away from the ventilation opening is thinner, the pulp film is blown to leak at the thick position where the pulp is blown, and the quality. In addition, the controllability of drying conditions in the drying process is poor, so that the water content of different areas of the reconstituted tobacco product is different, and the color consistency of the reconstituted tobacco product is poor.
Therefore, it is desirable to develop a device for preparing reconstituted tobacco for heating non-combustible cigarettes by using a thick slurry method, so as to improve the research and development efficiency of the reconstituted tobacco for heating non-combustible cigarettes, reduce the research and development cost and provide support for popularization and application of the reconstituted tobacco for heating non-combustible cigarettes.
